i have an i mac with MATSHITA DVD-R UJ-85J: as the superdrive. anyway as of late some times it will only burn 59 mb worth of musi and some times as much as 82 mb of music. then when i burn using MP3 it shifts the songs around in alphabetic order. any suggestions?? i have the burn speed down to 12x i have the newest itunes installed( i dont really like it but someone here downloaded it) any suggestions short of getting a new external drive??its driving me crazy. this has only started happening for the past few weeks. thanks in advance
